The GRACO 649217 is a conductive polypropylene air-operated double diaphragm pump with end flange, conductive polypropylene center section, acetal seats, Buna-N balls, and Buna-N diaphragm. It is designed for safe, efficient transfer of fluids in industrial environments, especially where static electricity or chemical compatibility is a concern.

Key Features:

• Air-Operated Double Diaphragm Pump
• Husky 1050, 1 in. (25.4 mm) flange
• Conductive polypropylene (center section and end flange), acetal seats, Buna-N balls, Buna-N diaphragm
• Suitable for a wide range of industrial fluids, especially where static dissipation and chemical resistance are required
• Stall-free, low pulsation air valve for smooth and rapid changeover
• Conductive polypropylene construction for static dissipation
• Buna-N diaphragm and balls for chemical compatibility and durability
• End flange design for flexible installation
• Up to 5 times longer diaphragm life compared to other double diaphragm pumps in its class
• 30% more efficient than market leader

Applications:
Ideal for transferring fluids in environments where static electricity buildup is a risk, such as chemical processing, paint, coatings, and other industrial applications. Suitable for use with a variety of fluids, including those requiring chemical resistance and static dissipation.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with existing equipment.
• Install a fluid pressure relief valve at the pump outlet to prevent overpressurization and rupture of the pump or hose
• Ensure proper alignment and secure mounting of the pump
• Follow all local safety and electrical codes, especially for conductive equipment
• Regularly inspect and maintain diaphragms, seats, and balls for wear and proper function
